Snowboard suspension system

ABSTRACT

A snowboard suspension system which comprises a mounting plate ( 27 ) which is connected to a binding plate ( 29 ) via one or more hinges ( 26 ). One or more dampers ( 30 ) situated between the binding plate ( 29 ) and the mounting plate ( 27 ) serve to dampen any compressive forces. A connection plate ( 31 ) may be added to produce a compound system.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation-in-part of U.S. patentapplication Ser. No. 09/105,974, filed Jun. 26, 1998, which applicationis a continuation of U.S. patent application Ser. No. 08/538,754, filedOct. 2, 1995.

FIELD OF THE INVENTION

[0002] This invention is related to shock absorbing devices forsnowboards, specifically to such devices which mitigate uneven terrain,while enhancing the performance of the snowboard.

BACKGROUND AND SUMMARY OF THE INVENTION

[0003] Snowboarding has evolved from a fledgling sport in the 70's to ahuge recreational and commercial enterprise in the 90's. There have beenmany recent advances in board and binding technology, but only one whichspecifically addressed the issue of shock absorption. This is simply ahigh-density foam pad which is mounted under the boarder's boot. Becausethis concept has been used in many other similar applications, it isn'tpatented. Quite frankly, it isn't effective either.

[0004] Although snowboarding is similar to snow skiing in many ways,there are some salient differences. Most notably, the boarder's legs arefixed in a transverse position on a single board, which precludes anyindependent movement of the legs. The boarder executes turns by anglingthe knees in concert with rotation and angling of the torso. As such,one can turn as quickly as on skiis, and, surprisingly, go just about asfast. Although the feel of charging down a slope is somewhat akin tosurfing a large wave, one does not have the convenience of simplyfalling off the board should a fall be in the making. Instead, theattached board can become a veritable torsion bar on the body, which hasresulted in a spate of injuries unique to snowboarders.

[0005] One of the primary causes of falls and snowboard-specificinjuries is bumps, and how the boarder negotiates them. Unlike inskiing, where the legs are independent, the boarder's legs are in afixed position, which reduces their available “travel”, or ability toabsorb the shock of a bump. Tearing of the collateral ligaments in theknee can result from pitching forward due to this decreased absorptivecapacity. A prime example of the need for additional shock absorption isapparent when snowboarding in fresh snow over a hard sub-layer. In thissituation, the whole body is constantly receiving unpredictable jolts.Thus, in the interest of preventing injuries, and adding a new dynamicto the “feel” of the board, I submit the following designs.

[0006] Since similar designs as those described for snowboards may beused for skiis and in-line skates, I have also covered thesepossibilities in this application. However, in the interest ofsimplicity, unless otherwise specified, all designs will be referred toas snowboard suspension systems.

[0007] Accordingly, several objects and advantages of the presentinvention are:

[0008] (a) to provide a simple means for absorbing shocks from bumpyterrain, while allowing for optimal edge control.

[0009] (b) to create an entirely new dynamic for the snowboarder—a morelively “feel”, and enhanced turning capability.

[0010] (c) to provide a means for the boarder to move forward on levelterrain without undoing the bindings, by “bouncing” the board back andforth—similar to what skateboarders do.

[0011] (d) to minimize the possibility of injury from roughterrain—decrease the amount of wear and tear on the boarder's body.

[0012] (e) to increase the possibilities in “freestyle” boarding, due tothe springier dynamic.

[0013] (f) to allow for a greater range of weight distribution andfore-aft transference of weight during a turn.

[0014] (g) to make the sport more appealing to older people, whosebodies aren't as resilient as they once were.

[0015] Still further objects and advantages will become apparent from aconsideration of the ensuing description and drawings.

[0016] In summary, the invention is a snowboard suspension system foruse with a snowboard that includes an elongate, flexible snow-planingmember, dual elongate bindings for receiving a user's boots, and wherethe long axis of the bindings are located at an angle relative to thelong axis of the snow-planing member. The snowboard suspension system ofthe invention includes dual suspension elements, each being coupled to acorresponding one of the dual bindings, and each suspension elementhaving a top surface, a bottom surface and a desired thickness, andbeing formed to compress a preselected amount when a suitable force isapplied to either the top or bottom surface. The invention also includesjoining means for coupling each suspension element to the snow-planingmember so that both suspension elements are linked by the snowboard.

[0017] The dual suspension elements may also each include a bindingmember with a long axis and securing means for attaching to acorresponding binding. The joining means may take the form of dualmounting members each with corresponding long axes and securing meansfor attaching to the snow-planing member so that the long axis of eachmounting plate is at an angle relative to the long axis of thesnow-planing member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0059]FIG. 1 shows an isometric of the preferred embodiment of thesnowboard suspension system of the invention at 10. Also shown areportions of a snowboarder's legs and feet A, the snowboarder's boots B,associated boot bindings C, and a snowboard D. Any conventional boots,bindings and snowboards are usable with the invention. Snowboard D maybe thought of as an elongate, flexible snow-planing member, and dualelongate bindings C are for receiving boots B. Corresponding long axes Eof the bindings are located at angles F relative to a long axis G of thesnowboard. System 10 includes fastener structure that preferably takesthe form of dual suspension elements 10 a and 10 b, each being coupledto a corresponding one of the dual bindings C.

[0060] Referring to FIGS. 2-3, the illustration of suspension element 10a is meant to be representative of both elements 10 a-10 b, where eachelement includes a top region or plate 12, a bottom region or plate 14and a desired thickness T (preferably between about 1- to 1.5-inches),and being formed to compress a preselected amount when a suitable forceis applied to either the top or bottom plate. Also depicted iscompressible section such as foam layer 16 and links such as bales 18.As shown in FIGS. 2-8, each bale is angled or canted so that it is notat 90 degrees with respect to a plane containing the snowboard. In FIG.2, an angle H depicts of less than 90 degrees, and preferably in therange of about 70-80 degrees, provides the proper bias towardcompression that allows system 10 to meet the above objectives. Thedimensions of plate 12 may be about 9-inches in length by about 6-inchesin width, and the dimensions of plate 14 may be about 9-inches in lengthand about 6.75-inches in width. These dimensions have been foundsuitable for conventional snowboards, but suitable changes in suchdimensions are possible.

[0061] Referring to FIG. 4, suspension element 10 a also includes firstjoining means or first joiners 20 for coupling each suspension element10 a (and 10 b, although undepicted in FIG. 4) to snowboard D (as shownin FIG. 1) so that both suspension elements are linked by the snowboard.First joiners 20 may also be thought of as screws or screw-serts, andpreferably take the form of 6 mm×16 mm stainless steel screws. Forreasons that will be described, either 3- or 4-screws are placed throughappropriately sized openings 22 a (oblong-shaped in cross section), 22 b(approximately circular in cross section) in plate 12 and in plate 14.

[0062] Referring to FIGS. 3-4, suspension element 10 a also includessecond joining means or second joiners 24 (again preferably screws—tworepresentative ones of the four are depicted) for attaching to acorresponding binding C (see FIG. 3) by placing the lead ends of thescrews through suitable openings in the bindings (see FIG. 3), andturning the screws into threaded fittings 26 (a representative one ofwhich is shown in FIG. 4) that are suitably fastened within openings 28formed in plate 12.

[0063] Still referring to FIGS. 3-4, the ends of each bale 18 are placedthrough corresponding cylindrical sleeves such as sleeve 30 in eachplate 12, 14, with each sleeve suitably fastened within cylindrical baleopenings, such as opening 32 formed in each plate 12, 14. The ends ofeach bale 18 are circumferentially notched to allow placement of awasher 34 and lock washer 36 to hold each bale in the desired positionwithin each sleeve. If each plate is formed by molding a suitablecomposite material, it has been found that reinforcing the length ofeach cyclindrical opening that receives a sleeve like sleeve 30 withangled, linear sections 38 will tend to limit shrinkage and ensureproper location of bale openings in the finished plate. Recesses 40 arepreferably square in cross section and allow access to the ends of thebales for placement/sliding movement of washers 34 and lock washers 36.Recesses 42 are the usual types of recesses when forming the plate fromspheroidal elastomers. Recesses 44 are provide a distinctive look toplate 12 and are ornamental.

[0064] Referring again to FIG. 4, a suitable adhesive layer 46 isapplied to the top surface of foam layer 16. It is possible to use anysuitable means to attach foam layer 16 to one or both plates 12, 14.Suitable openings 48 are formed in foam layer 16 to allow screws andscrewdrivers to pass therethrough to attach plate 14 to snowboard D (seeFIG. 13).

[0065] Referring to FIGS. 5-8 and 14-15, arrows are shown to illustratethat system 10 will result in the same controlled, horizontal, planarcompression between plates 12 and 14 regardless of whether thesnowboarder puts toe pressure (FIG. 6), heel pressure (FIG. 7), side (ofboot or boots) pressure (FIG. 8), or toe-and-heel pressure (FIG. 15) onthe plates.

[0066] Referring to FIGS. 9-10, two alternate embodiments of thesuspension system of the invention are shown. In FIG. 9, suspensionelement 110 a is formed integrally by extruding suitable syntheticmaterials to form links 118 integral with plates 112 and 114 thatsandwich a foam layer 116. Plate 114 is suitable attached to snowboardD, and plate 112 is suitably attached to binding C as shown anddescribed above. In FIG. 10, plate 14 is replaced by dual elongatepanels 214 that are formed of a suitable material and include openingsfor receiving and suitably holding corresponding ends of bales 218.Bales 218 should be positioned at an angle H as described in connectionwith FIG. 2.

[0067] FIGS. 11-12 show the reason for constructing plate 14 with the5-hole pattern of holes 22 a and 22 b. The result is to allow for the3-screw (FIG. 11) or 4-screw (FIG. 12) combinations which willaccommodate attachment to the two types of hole patterns that snowboardmanufacturers presently use when manufacturing snowboards. Byconstructing plate 14 as shown, there is no need for drilling additionalholes in the snowboard when attaching suspension elements 10 a and 10 b.

[0068] Referring to FIG. 13, one can see how plate 14 can be attached tothe snowboard by manually compressing plates 12 and 14. The result is toalign holes 22 a and 22 b in plates 12 and 14 (and corresponding holesin foam layer 16) to allow screws and a screwdriver to fit therethroughfor tightening screws in the desired holes.

[0069]FIG. 17 shows the most elemental version of the snowboardsuspension system. It is simply a piece of springy material bent to forma mounting plate 327, and binding plate 329. The fulcrum is a springhinge 325. It may be fabricated from spring steel preferably stainless),or some form of composite with fiber reinforcement. A bottom stop 323may be placed anywhere between the hinge and distal end of the mountingplate 327. Another version incorporates a regular hinge 326 as thefulcrum (as in FIG. 18), and a damper 330 may be included as areplacement for the spring hinge 325. All the figures on sheet 7 dealwith simple snowboard suspension systems, as opposed to the compoundsnowboard suspension system shown in FIGS. 22 and 23. In all cases, thesnowboard suspension system is mounted between the board and theboot/binding.

[0070]FIG. 19 demonstrates the placement of a hinge-type snowboardsuspension system with dampers and baffles. Any of the other versionsexcept for FIGS. 27 and 28 have similar placements.

[0071] The cant pictured in FIG. 20 can be made out of any water andtemperature-resistant high durometer (preferably over 80) material. Itmay be a simple angle, or a compound angle, usually between 4 and 15degrees, depending on the preferences of the boarder. All boot/binding324 systems are mounted on the top of the binding plate 329.

[0072] In the hinge-type snowboard suspension system with damperpictured in FIG. 18, a damper connector 328 may be used to connect thebinding plate 329 with the damper 330 in any fashion which maximizesvertical movement of the binding plate 329. The damper 330 can be avariety of things—air/oil shocks, rubber, elastomers, springs, airbladders—any combination or anything which is resilient and has reboundcharacteristics. Attachments of the boot/binding 324 to the bindingplate 329, or the mounting plate 327 to the board 322 are achievedthrough the standard means—screws, slots, glues, or any other strongfastening systems. Current systems for attaching bindings to snowboardsare adequate.

[0073] The compound spring-type snowboard suspension system pictured inFIG. 22 is the same material as the snowboard suspension system picturedin FIG. 17, but configured in an S curve, so as to provide verticalcompression to the side of each angle. This increases the availabletravel and allows for a more level binding plate 329.

[0074] In the compound hinge-type snowboard suspension system in FIG. 23the mounting plate 327 is articulated with the connection plate 331 viaa hinge 326. The connection plate 331 then articulates with the bindingplate 329 via another hinge 326. On one side (in this case the left),there is a damper 330 between the binding plate 329 and the connectionplate 331. On the other side, there is another damper between theconnection plate 331 and the mounting plate 327. These dampers arecomprised of the same materials as previously described. They may alsobe connected to the plates (327, 329, 331) via damper connector 328 typepieces, such that maximum vertical travel is facilitated. Placement ofthe damper 330 so that a cantilevered configuration is achieved is alsopossible.

[0075] In the scissor-type snowboard suspension system pictured in FIG.24, the mounting plate 327 is connected to two scissor alms 333 viahinges 326. They cross each other at another hinge 326, and then connectto the binding plate 329 via two more hinges 326. Horizontal movement ofboth ends of the scissor alms 333 is accomplished through anything whichallows the hinge free horizontal movement, while limiting lateral andvertical play. There are many possible permutations of this design toobroad to cover, thus the illustration and description are simplified.

[0076] The telescoping snowboard suspension system pictured in FIG. 25incorporates two telescoping dampers 334 between the mounting plate 327and the binding plate 329. The attachment in both these areas is verystrong, to limit any lateral play (a must for edge control), whileallowing for vertical travel. Ideally, they should be very similar tothe front forks on a motorcycle—a damping member which slides back andforth on a piston or plunger. As long as the telescoping members aremachined to close enough tolerances (in the 0.008-0.014 range) thedamping mechanism within each telescoping damper 334, can be any of theaforementioned materials—coil springs, elastomers, air/oil combination,or simply air pressure.

[0077] In the parallelogram-type snowboard suspension system pictured inFIG. 26, the mounting plate 327 articulates with the slanted arms 335via hinges 326. The hinges 326 also serve to connect the binding plate329 with the slanted arms 335. A damper 330 may be placed between themounting plate 327 and the slanted arms 335, or the binding plate 329and the slanted arms 335. Anything which allows for damping of thevertical movement of the binding plate 329 is fine. The dampers 330 maybe any of the aforementioned materials.

[0078] In the cantilevered full-length snowboard suspension systempictured in FIG. 27, both boot/bindings 324 are mounted on a singlebinding plate 329. This articulates with the mounting plate 327 via abroad hinge 326. A damper 330 can be placed anywhere between the hingeand the mid-section of the binding plate 329 to maximize thecantilevered effect. As an alternative, the damper may also be placedtowards, or beyond the end (and attached via a damper connector 328) ofthe binding plate 329.

[0079] With the hinge-type suspension system with damper adapted to finin-line roller skates pictured in FIG. 28, there are several specialdesign considerations. As the hinge must be decreased in width (toroughly the width of the wheels, compared to the width of a snowboard),it isn't as inherently strong as with the snowboard, and must thereforebe of larger diameter. Also, the binding plate 329 and mounting plate327 must be thicker in order to counter the lateral thrust which isapplied from the skater's stride. A piston-type air/oil damper 330 isthe best choice for shock absorption and rebound. The shaft of thepiston allows for increased lateral control and stability. More springand less dampening are desirable qualities of the damper 330, as it'simportant not to absorb, but enhance the lateral thrust from theskater's stride. Top and bottom attachments of the damper 330 must be ofsufficient strength to minimize lateral play during the stride.

Operation

[0080] The central concept of the various versions of the snowboardsuspension system is to allow for vertical travel of the boot/binding324, while limiting any horizontal movement or rotation. This gives theboarder the advantage of having bumps dampened, while still allowing formaximum edge control. All the versions illustrated address this dynamic,with varying degrees of shock absorption and damping.

[0081] In each of the designs illustrated on page one, the binding plate329 moves radially in relation to the hinge (325, 326), decreasing thedistance to the mounting plate 327, thus absorbing shocks that wouldnormally be felt by the boarder. A bottom stop 323 may be incorporatedto prevent the binding plate 329 from bottoming out on the mountingplate 327. Also, a baffle system made of rubber or some other flexiblematerial may be placed between the binding plate 329 and the mountingplate 327 in order to prevent the buildup of ice or snow.

[0082] The compound spring-type snowboard suspension system pictured inFIG. 22 works similarly to the first two, but adds another curve toallow for more travel.

[0083] All the snowboard suspension systems pictured in FIGS. 23-26 havethe advantage of maximum travel coupled with relative constant fore-aftangle despite compression of the binding plate 329. Of these, the hingedcompound snowboard suspension system with dampers (pictured in FIG. 23)is the most simple, and is thus the preferred embodiment. Any verticalforces are dampened by the angle of the connection plate 331 becomingmore acute from the dampers 330 compressing, thus allowing the bindingplate 329 to move towards the mounting plate 327.

[0084] The scissor-type snowboard suspension system pictured in FIG. 24allows for vertical travel of the binding plate 329 by increasing theacute angle on the scissor arms 333. In the telescoping-type snowboardsuspension system pictured in FIG. 25, the binding plate 329 moves inrelation to the mounting plate 327 via telescoping dampers 334.

[0085] In the parallelogram-type snowboard suspension system pictured inFIG. 26, there is a great possibility of vertical travel as long as thedamper(s) 330 are mounted outside of the slanted arms 335, in order toprovide clearance.

[0086] In the cantilevered full-length snowboard suspension systempictured in FIG. 27, the binding plate 329 moves radially in relation tothe hinge 326, decreasing the distance to the mounting plate 327. Thecantilevered damper 330 allows for vertical travel. The designapproximates the “feel” of a standard board, due to both bindings beingmounted on the binding plate 329, instead of moving independently. Thisis neither an advantage or disadvantage, simply another choice for thosewho prefer it. In order for this to work optimally, the mounting plate327 must extend to the area below where the rear bindings 324 aremounted. The mounting plate must also be of a semi-flexible material, inorder to allow for free flexion of the board.

[0087] In each version the boot/binding 324 is always mounted on thebinding plate 329, and the snowboard suspension system is secured to thesnowboard 322 via the mounting plate 327. This allows for after-marketfitting of snowboard suspension systems, in addition to fitting rightfrom the factory. As previously mentioned, either “soft” or “plate”bindings may be used.

[0088] Use of these snowboard suspension systems is very simple. Theboarder simply attaches the boot/bindings 324, and proceeds as theywould on a standard board without snowboard suspension system, exuberantwith the enhanced “feel” of the board.

[0089] The suspension system for in-line roller skates pictured in FIG.28 is well-suited for inclusion in production skates. However, there aresome possibilities for after-market products. Anything which allows fora flex-free connection between the bottom of the boot 324, and thebinding plate 329 is fine. One possibility is to offer a system whereinthe hinge 330 and mounting plate 327 are an integral unit, and can bechanged on a given skateboot by removing them at the hinge 330, andreplacing them with a similar assembly that offers different performancefeatures.

Conclusion, Ramifications, and Scope of Invention

[0090] There are many possibilities for further elaborations of thesebasic designs. In terms of materials usage, the most desirablecombinations would be those that offer lightweight and strength. Any ofthe carbon fiber reinforced composites, or alloys would fit the bill.Whatever material is used should be resistant to temperature extremes,UV radiation, corrosion, chipping, breaking, or other forms ofbreakdown. All fittings should be stainless tell, or some othercorrosion-resistant material. The actual snowboard suspension system maybe mounted with the fulcrum or hinge 326 mounted towards the front orback. This is largely dependent on fore-aft angular considerations ofthe broader. A baffle 321 system may be incorporated in order to keepsnow entirely out of the area of compression. A variety of dampers 330may be used, ranging from simple air bladders to sophisticated air/oilshocks and torsion bars. A configuration which allows for progressivedamping by combining various dampers 330 is the most desirable. The“feel” of the snowboard suspension system will be determined by therelative springiness and travel of each configuration. Every snowboardsuspension system could be custom-tailored to the individual boarder byadjusting vertical travel, springiness, damping, sideways deflection,and placement of the snowboard suspension system on the board. Thesefactors would be influenced by the boarder's skill, weight, interests(e.g. freestyle or racing), and preferred terrain.

[0091] The hinged and hinged-compound type snowboard suspension system(as in FIGS. 18 and 23) are the most flexible in terms of allowing forthe aforementioned customized configurations. As such, they are thepreferred embodiments. By adjusting the placement of the dampers 330relative to the hinges 326, first through third class levers can beincorporated. In addition, by varying the durometer of each damper 330,progressive rebound and damping can be attained. Different durometerdampers 330 may be used on front and back, depending on the conditions.A cantilever-style configuration is the most desirable in terms ofmaximizing the amount of travel in relation to compression of the damper330. For the current use, compression-type dampers 328 would bepreferred over elongation-type dampers. Any other design considerationswould be dictated by cost, available materials, and desired performancefeatures.

[0092] These types of suspension systems can also be adapted to fitdownhill skiis. The only real difference is a greater emphasis oncontrolling fore-aft flexion, which has been done with the designspictured in FIGS. 23-26. Not only do these systems allow for increasedshock absorption, but, as with snowboards, they alter the “feel” of theskin in rather interesting ways.

[0093] The hinge-type snowboard suspension system with damper adapted tofit in-line skates (as pictured in FIG. 28) is a significant improvementover current fixed systems insofar as it dampens shocks andsignificantly enhances the feel of the skates due to the rebound effectand energy return. Alterations may be in the form of the other designsdescribed herein. The fulcrum, or hinge 326 may be placed further back,and a damper positioned in front, as well as behind it. A lock-outmechanism could be incorporated which keeps the suspension system fromworking, should that be desirable. Various damper 330 combinations couldbe offered for different weights and abilities.

[0094] Accordingly, the reader will see that the various designs for asnowboard suspension system covered by this application have thefollowing advantages over current board/binding configurations:

[0095] They provide a way to quickly customize the feel of the board.

[0096] They minimize the possibility of injury from rough terrain.

[0097] They provide a means for the boarder to move forward on levelterrain without undoing the bindings, by “bouncing” the board back andforth—similar to what skateboarders do.

[0098] They create an entirely new dynamic for the snowboarder—a morelively “feel,” and enhanced turning capability.

[0099] They provide a simple and effective means of absorbing shock frombumpy terrain for snow boarders, skiers, and skaters alike.

[0100] They increase the possibilities in “freestyle” boarding, due tothe springier dynamic and adjustability.

[0101] They allow for a greater range of weight distribution andtransference of weight during a turn.

[0102] they make the sport more appealing to older people, whose bodiesaren't as resilient as they once were.

[0103] Although the description above contains many specificities, theseshould not be construed as limiting the scope of this invention, but asmerely providing some illustrations of some of the presently preferredembodiments of this invention. The basic concept of a binding plate 329which moves vertically in relation to a mounting plate 327 and has ameans for damping or enhancing this movement is the central feature ofthese designs. To my knowledge, there are no precedents in the prior artwhich these designs emulate. Thus the scope of these designs should bedetermined by the appended claims and their legal equivalents, ratherthan by the examples given.
